Chronotron Speed Changer is an audio/video speed changer app optimized for touch devices. It allows you to manipulate tempo and pitch independently during playback, i.e. change the tempo of audio and video files without affecting pitch (time stretching) and/or change pitch without affecting tempo (key change).
The innovative HOLD mode virtually lets you step note by note during playback (even backwards!) so you can transcribe ultrafast guitar solos easier than ever.
You can use Chronotron Speed Changer to slow down audio and video material for easier music and speech transcription, to transpose backing tracks so you can sing along in a
more comfortable key, to change tempo when practicing complicated dance steps, or just to have fun with it.
